Please help, new rig hitching in all games

I just put together a new computer and am getting hitching in all the games I've tried.

Specs:
i7 3930k
ASRock Extreme6
32GB (8x4GB) Corsair Vengeance
EVGA GTX 680 SC 2GB
Samsung 840 250GB SSD
Corsair HX650 PSU

In Far Cry 3 I get hitches when looking around in different directions.
In Planetside 2 I get hitches when looking in different directions and when scoping with a sniper rifle. Seems like when it's rendering new terrain.
In CS:GO I get hitches in almost every engagement, when there are players on screen and they are shooting. Lowering my graphics made it a little better but didn't fix it.

Other info:
Have all drivers for mobo installed
Running 310.64 Nvidia drivers
Problem happens with default settings and with overclock

If anyone has any ideas I'd greatly appreciate it. This is extremely frustrating.
